Episode 3 video 👉 kzread.info/dash/bejne/hIGAyaeGnJbYf9I.html Nice to see you all participating. The anode metal i used is aluminum. It looks like that because i started working on air batteries around 3 months back, and that's when i poured Koh on it because of which it lost its shine. Yes, i also tried aluminum heat sinks as the electrodes, and i got the same result as I am showing here. Same for the aluminum line cables as electrodes. For me, Vmax was 1.7v per cell in one of my experiments under some very specific conditions. It's not shown in the video.

Would you possibly know how does Naoh compare to koh for electrolyte in these cells? I know it's simple enough to convert one to the other but just wondering for simplicity's sake. I can find Al and graphite on the streets picking up scrap all day and can buy a lb of Naoh at Wally world for ~6$ just koh is slightly less accessible

no, it's aluminium but that is not an aluminium-air battery but a voltaic pile. The aluminium has about -1.7V electrochemical potential and the carbon is just an hydrogen electrode which has a potential around -200mV because the electrolyte is alkaline so, the open circuit potential is about 1.5V. The indian knows nothing about electrochemistry.

The problem with this battery is the aluminium will be destroyed by the electrolyte very quickly no matter if you draw current or not. Probably you should remove the hydroxide electrolyte when the battery is in storage.

Thanks for sharing for your bright idea about cell battery and we are been interested and padticipate as in commenting,..in my comment why you called it air battery? and my thought you make 1 cell that produce an output of 4.2 volts, thanks anyway and keep strive friend👍

This is really great, aluminum-air batteries look incredibly promising, i appreciate you providing excellent information on it. I have a question though, are the three carbon brushes per cell necessary? What would be the effect of less? Are you mostly just trying to get more surface area? I can't want to test this chemistry myself, but i'm tinkering with zinc-iodine batteries right now, i dont want to get too far ahead of myself!

É o gás que reduz a capacidade da célula produzir intensidade. As bolhas ao formarem-se afastam o electrólito das paredes do eletrodo de alumínio reduzindo a superfície de contacto/ área activa. Há substâncias que absorvem o hidrogénio. Nas pilhas zinco-carvão é o dióxido de manganês que é o despolarizador de forma a impedir que o hidrogénio isole o eléctrodo. Aumentar a área dos eléctrodos aumenta a capacidade e a intensidade.

Если вместо раствора щелочи КОН использовать окислитель, например, хлорку, содержащую гипохлорит, то выделения водорода не будет происходить. Напряжение так же будет выше, примерно 2,2 В. Такие элементы используются в реальности. Для эффективной работы и большого выхода тока важна развитая поверхность алюминия и небольшое расстояние между электродами.

I don't remember, but that part should be in this video or its third part.

h20 + koh + aluminium = hydrogen gas ...this is how we make H gas in high volumes very quickly! Safer, less reactive to use sodium sulphate?

try carbon fiber cloth instead, much simpler to use, resistance of graphite cloth is very low, close to zero, same as those brush carbon blocks. baking soda works even better, for aluminium-air and is non-toxic. also baking soda reacts less with the aluminium, mostly removing the aluminium oxide only, very different to potassium hydroxide, which actively produces hydrogen from the aluminium.
